TUBE-WINDING MACHINE.

Specication of Letters Patent. Patented Sept, 26,', `191,1, Applicationled October 3, 1910. Serial No. 584,969.

To all whom 'it may .v

Be it known that I, CHARLES F. WELSH,

. a citizeniofthe United States, residing at Y and ldeclare the followinto be a'full, clear,-

Detroit', county of Wayne, State 'of Michian, have invented a certainnew andv useful mprovement in Tube-Winding Machines,

and exact description o the same,I suchas *will enable others skilled inthe art to which itpertains to make and use the same, reference beinghad to the accompanyin draw- '.ings, whichA form a part of/this specication. This inventionrelates to tube-wlndl'ng machines.

It has for its object an improved machine f -for winding .what-are knownas spirally wound tubes; in the construction of devices of this class aribbon of 'paper is wound spirally around a :mandrel by revolving themandrel on its axis and drawing the ribbon of' paper from itsstorageroll as it is used in the construction of the tube; the tubeunderjcnstruction is pushed oil' from the free end. of theman'drel andis'cutinto lengths to produce the commercial tube or box. The windingribbon is held lirmly against the mandrel or against an under-'lyingpart of -the ribbon by beltsy that cross the mandrel obliquelytheretoand thenressure of the belt serve sto press the paste or gluedsurfaces of the ribbon into close contact.

The main object Vof this invention relates 'tomeans for adjusting theseobliquely lying beltswhile maintaining their dr1v1ng mecha- -vation ofthe 'mam drivi nism in proper relationtherewith.

In the drawing :-Figure 1, is a plan view of the machine. F-i 2, is across section at the line 2-2of Flg. 1. Fig. 3, is a hori i the pressurebelts.

On a frame A is mounted a master wheel lion a shaft 2L On the shaft is amiter wheel 2HL which ears with a miter wheel -3 on the vertical s aft 3and drives the same, thereby transmitting motion tomiter Wheels 4 and 5and driving horizontal shaft 6 which .extends to the side of the frame'and has mounted upon it amiter'wheel 8iarranged to slide longitudinallyof the shaft 6 ,and

meshes with miter wheel 9 on shaft 10. The

shaft 10 is carried in, bearings which4 will be hereinafter describedland is capable of ,l

lateral movement with respect yto the frame A. The two wheels 8 and 9are yoked by a yoke 11 that holds them at all times in mesh slidingihe:wheel son its `sima et@ correspond with theflateral movement of theshaft 10, The shaft lis'carried at .the end of Vtwoparallel membersoscillating 12 and-12, these two members and the various attachments tothem are 'similar` in all respects, and only' one 'of them will be described, with the understanding that thesecond one, is exactly similarto the one described,y and that the indicating numerals .on the secondmember 128L are similartothe numerals on the Vmember described. with theexception that each one has an alphabetical character connected with itto distinguish it from the corresponding number .on the memberdescribed.V The member 12 is pivotally supported on the crosspart Bofthe frame and held thereto by a bolt 14 and nut 15. The bolt 14terminates at its head end with a cap which engages over a raised ring16 on the member 12, vand the entire member 12 oscillates the member B,Vand is actuated in its oscillating movement by parallel rod 17 thatcouples 12 and 12, and isy provided with a rack 19that enga es withdriving gear 20 on a shaft actuated y hand winch 18. The shaft isjournaled inthe main frame A. The oscillating cross mem ber 12 carriesat one end. a stud 21 which carries a miter wheel 22.` The stud iscoupled tol the shaft 10 lby `yoke 24 pivotally.y

connected to the stud and slidingly connected to the shaft. Mountedslidingly on the shaft is a initer wheel 25 arranged to be held in meshwith the miter wheel 22 bymeans of the yoke .24. A cross shaft 26journaled in the stud 21. and ina similar but sliding stud 27 at theopposite end 'of the member 12 is connected by miter vgearing to thegear 22 and to a similar gear 28 mounted on a shaft journaled in thestud 30. The gears 22 and 28 are on vertical shafts journaled in thestuds 2l and' 30 and these vertical shafts carrybelt wheels 31 and@mounted to bear against the mandrel with the already formed tubeinterposed between the mandrel and the rolls, and to press .downstrongly the edges of the ribbon and smooth the edges into. a continuoussurface or to smooth down. and press out t-he cement, glue or othersubstance that may be used, andmay have, because of thel previouspressure, eXuded slightly along the edges of the ribbon. A tube severingappliance islpreferably attached and is indicated under the generalcharacter C, but is not further referred to because it forms no part ofthe present invention.

The two pressure belts are driven by the shaftl 10 and inasmuch as it isdesirable to change the angularity of the pressure belt to conform tothe width of the ribbon that is used, and to the size of the mandrelthat is employed, it isnecessary to provide not only for the adjustmentof the tension of the belts but to provide for driving them throughoutthe extent ofthe change of angularity that may be given to them. Inchanging the angularity of the member 12 the stud which carries the beltwheels changes its absolut-e distance from the'aXis of the mandrel 4,and the shaft 10, which is parallel tothe -aXis of vthe mandrel 4: mustchange Vits absolute distance therefrom in the same amount. This isprovided for by swinging the Ashaft 10 with the member 12 and makingsuitable provision to maintain kin mesh the gear' which drives the shaftA10,

Athe miter Wheel 8 on'its own shaft which.

is accomplished without losing its engaging relation with the miter gear9, and the some- 1,oo4,121 l what similar yoke couplings 24 slide on theshaft 10 while remaining in pivotal-connection with the 4stud 21 andserving to maintain the intermeshing gear 22 and 25 in connection whilethe stud 21 serves to maintain the connection between the bevel gears 22and shaft 26.

What I claim is l. In a tube-forming machine, the combination of asupporting frame, a mandrel, an oscillating member angularly adjustableacross said mandrel and pivoted to said frame,l shafts, one of which isprovided with a miter gear carried'by said soscillating mem-ber andhaving pulleys mounted thereon, a belt carried'by said pulleys andengaging around said mandrel, a -drive shaft having a miter wheelthereon,a miter gear.

splined on said drive shaft and intermeshing with said gear on saidpulley shaft, means for holding. said gears in intermeshed relation, asecond drive shaft disposed'at right angles tothe first-mentioned dr'veshaft and having a miter wheel splined t ereon intermeshing with themiter Wheel on vthe firstmentioned drive shaft, means for holding saidmiter wheels' in intermeshed relation and means for rotating said seconddrive f'shaft, substantially as described.

2. In a tube-forming machine, having a suitable windingapparatus adaptedto oscillate, :rgear thereon, a driving shaft having adrive connectionwith said gear movable lengthwise said shaft, a second driving shaft atright angles to said vfirst driving l shaft `and'having a driveconnection therewith movable lengthwise along said second vso shaft,whereby the gear o'n said winding apv paratus may assume any point inthe arc through lwhich it oscillates and he drive connections willadjust themselv s thereto without the shafts changing their angularrelation, substantially as described.

In testimony whereof, I sign'this specii-` i cationin the presence -oftwowitnesses.
